✦ Synopsis
Poly vinyl alcohol (PVA) dissolves large amounts of lithium salts (up to about 1.5 g/g of PVA) such as LiCF3SO3, LiClO4 and LiBF4 in its polymer matrix. The composites obtained show good ionic conductivity. When the PVA-lithium salt composites are used as the solid electrolyte in solid-state electric double-layer capacitors with porous and electrically conducting clay-carbon composites as polarizable electrodes, the solid-state electric double-layer capacitors show good charge/discharge behavior with large capacitance of 2.5-3.5 F/(cm a of the capacitor).
